Specification of Letters Patent.

Patented'July 18-, 1916.

Application filed May 26, 1915. Serial No. 30,643.

To all whom it may concern:

Be it. known that I, LEWIS K. WARNER, a citizen of the United States, residing at Lexington, in the county of Dawson and State of Nebraska, have invented a new and useful Tank, of which the following is a specification. 7

This invention relates to metal tanks and one of its objects is to provide a sheet metal tank made up of sections which can be nested together so as thus to reduce the cost of transportation, and which are so constructed as. to be easily assembled, the oints produced being leak proof and being of such strength that live stock standing in the tank will not injure the joints andcause leakage therealong.

A further object is to provide tank sections so constructed that they will not be injured at the angles thereof while belng transported, as is often the case where the parts are soldered together prior to shipment, the rough handling causlng the olnts to break open along the soldered P01110118.

With the foregoing and other objects 1n view which will appear as the description proceeds, the invention resides in the c0m-- bination and arrangement of parts, and in the details of construction hereinafter described and claimed, it being understood that changes in the precise embodiment of the invention herein disclosed, can be made within the scope of what is claimed, Without departing from the spirit of the invention.

In the; accompanying drawings the preferred form of the invention has been shown. I

In said drawings :Figure 1 isa perspective view of a portionof a tank embodying the present improvements. Fig. 2 is a plan view of the tank. Fig. 3 is an enlarged section on line A-B Fig. 2.

Referring to the figures by character of reference 1 and 2 designate opposed sections of a sheet metal tank. The bottom of section 1 is folded along the free edge thereof to form a flange 2 of double thickness, this flange merging into an upstanding inverted channel portion 3 terminating in a base flange 4 which is fastened upon the bottom of section 1 in any preferred manner, as by means of rivets 5, solder, or both. The space Within the inverted channel portion 3 is filled by a flat metal bar 6 which is placed in position at the time of bending the metal. The upstanding edges of the wall of section the channel-members 8 upon said bottom and wall.

The section 2 of the tank has its free edge.

portion offset upwardly to form a longitudinal recess 8 thereunder, this upwardly oflset portion being overhung by an inverted channel portion 9 integral therewith, there being a flange 10 along the inner side of the channel portion and which is secured to the bottom of section 2 by rivets, solder, or both. The space within the channel portion 9 is filled by a flat bar 11 of suitable metal.

The upstanding edges: of the wall of section 2 are constructed in the same manner as the described portion of the bottom of said section and bracing plates 12 are secured to the angle portions, as in section 1.

Openings 13 are formed transversely within the upstanding channel portions 3 and 9 and the bars therein, the openings in the upstanding portions of section 1 being adapted to register with the openings in the that the same can be more readily handled and will occupy less space than Where a complete tank is shipped. Furthermore 90 there are no joints liable to break open during transportation and thus render the tank unfit for use when set up. I

In setting up the tank the flange 2 is inserted under the offset portion of the bottom of section 2 and a strip 14 of-suitable packing material is interposed between the up standing portions 3 and 9. Bolts 15 are then inserted through the registering openings 13 and, when tightened, will clampthe parts securely together, thus forming a leak-proof joint. Importance is attached to the fact that the inwardly extending parts of the joints are reinforced by the inserted bars 6 and 11. This prevents injury to the jOlIII: should live stock stand within the tan corresponding portions of section 2. When The braces 7 and 12 prevent lateral dis- I tanks that would otherwise be too large to pass through the door of a car.

A further advantage resulting from the structure herein set forth is. that should the solder which holds the flanges 4 and 10 in position, crack or break, it would not result in the tank leaking, as the water would meey flow into the inverted channels 3 an Although the bottom of the section 2 has been shown offset in Fig. 3, this is not necessary under ordinary conditions Where the tank is formed of Very thin sheet metal.

What is claimed is z- I 1. A sheet metal tank comprising opposed sections, inwardly extending channel portions along the free edges of the sections, reinforcing bars seated within the said channel portions, means for fastening the channel portions of the two sections together, and a longitudinal flange outstanding from the channel portions of one section and adapted to be lapped by the opposed section.

2. A sheet metal tank comprising opposed sections, the free edge portion of one section being folded to form an outstanding longitudinal flange, an inwardly extending 1nverted channel portion,

and an attaching the free edge portion of the other section being bent to form an ofiset portion, an inwardly extending channel portion, and an attaching flange, and reinforcing bars filling the channel portions on the two sections.

3. A sheet metal tank comprising opposed sections, the free edge portion of one section being foldedto form an outstanding longitudinal flange, an inwardly extending inverted channel portion, and an attaching flange, the free edge portion of the other flange,

section being bent to form an offset portion, an inwardly extending channel portion, and an attaching flange, reinforcing bars filling the channel portions on the two sections, a packing material interposed between the channel portions of the two sections, and means extending trang ersely through said channel portions and bars for binding them upon the packing material.

In testimony that I claim the foregoing as my own, I have hereto afiixed my signature in the presence of two witnesses.
